EMANE event service port number not used when CORE generates location events #150

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create scenario using an EMANE model
2. Under "EMANE options", change the "Event Service group" to a different port 
number e.g. 47509
3. If a default route exists for eth0, run two tcpdumps:
   tcpdump -nli eth0 port 47503
   tcpdump -nli eth0 port 47509
4. Start the scenario and drag a node on the canvas. CORE generates EMANE 
events using port 47503 instead of the configured 47509. The emane process is 
listening on 47509 and does not receive these location events. Verify using 
'netstat -unl'.

as a side note, I wonder why these are showing up in my 'netstat -unl' output:

EmaneNode.setnemposition() uses session.emane.service to publish location events

Emane.service = emaneeventservice.EventService() is set during init()

This needs to be moved to EmaneNode.service (it's a per-EmaneNode port setting.)
A libemaneeventservice.xml file needs to be written to the /tmp/pycore.nnnnn 
sessiondir.
The LIBEMANEEVENTSERVICECONFIG environment variable needs to point to this file 
prior to creating the EventService object.

fixed in r493

Added buildeventservicexml() that writes 
/tmp/pycore.xxxxx/libemaneeventservice.xml file if the default group or port 
are changed.
Dynamically set LIBEMANEEVENTSERVICECONFIG environment variable when needed
to load the event service library XML.
